Matthew,

Thanks,

Why not just rephrase the paragraph so that it does not appear to prescribe 
protocol development, but rather scopes the solutions to those that the IETF 
traditionally deals with and that meet the requirements/gap analysis?:

"NVO3 will consider an approach to multi-tenancy that uses a Layer 3 
encapsulation rather than relying on traditional L2 isolation mechanisms (e.g., 
VLANs) to support multi-tenancy, and consistent with a requirements gathering 
and gap analysis exercise. The approach will provide an emulated Ethernet 
service capable of satisfying typical data center deployments."


[JD]   I also have a problem with the last sentence as it sounds as though NV03 
will be encroaching on the charter of the L2VPN WG, which reads, in part:



"The L2VPN working group is responsible for defining and specifying a limited 
number of solutions for supporting provider-provisioned Layer-2 Virtual Private 
Networks (L2VPNs). It will also address requirements driven by cloud computing 
services and data centers as they apply to Layer-2 VPN services."



And:



"5. Ethernet VPN (E-VPN) - An enhanced Layer-2 service that emulates an 
Ethernet (V)LAN across a PSN. E-VPN supports load-sharing across multiple 
connections from a Layer-2 site to an L2VPN service. E-VPN is primarily 
targeted to support large-scale L2VPNs with resiliency requirements not 
satisfied by other L2VPN solutions."
